Good Luck Comes from Heaven, I Am Bound to the God-Level Cashback System

The system is a auxiliary, not a fun story. The plot is unpleasant, and it is about the changes that happen to ordinary people after good luck comes from heaven. "You really are the system, you didn't lie to me!" "Of course, will you eat if I lie to you?" "No, am I still hungry?" "That's it, are you willing to bind to this system?" "Yes, I definitely am willing!" "Bind immediately!" Then a voice came from Fang Ye's ear. "Congratulations on the successful host binding!" "The host can then use this system's super cashback!"
